一.准备maven项目

mvn archetype:generate -DgroupId=com.lsf.app -DartifactId=coder-center -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false       创建coder-center项目，服务的具体实现

mvn archetype:generate -DgroupId=com.lsf.app -DartifactId=coder-center-api -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false  创建coder-center-api项目，暴露服务

mvn archetype:generate -DgroupId=cn.lsf.app -DartifactId=appserver -DarchetypeArtifactId=maven-archetype-webapp -DinteractivMode=false   创建appserver  web项目，消费各服务

注释：

mvn archetype:generate　　    固定格式

　　-DgroupId　　　　　　　　　组织标识（包名）

　　-DartifactId　　　　　　　　项目名称

　　-DarchetypeArtifactId　　  特定ArchetypeId，maven-archetype-quickstart，创建一个Java Project；maven-archetype-webapp，创建一个Web Project

　　-DinteractiveMode　　　　　　是否使用交互模式

然后把项目导入Eclipse中，项目结构图如下

二.服务提供者

1.在coder-center-api中定义接口，用来暴露出去

package com.shengfeng.user.service;import com.shengfeng.user.bean.UserBean;public interface UserService {long addUser();UserBean getUserByUserId();
}

2.在coder-center-api中定义bean，用来暴露出去

package com.shengfeng.user.bean;
import java.io.Serializable;
public class UserBean implements Serializable{private static final long serialVersionUID = -5621716534400078000L;private long id ;private String  username;//用户名private String password;//密码private String level;//等级private int sex;//性别private String mobilephone;//手机号private String img;// 头像public long getId() {return id;}public void setId(long id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String getLevel() {return level;}public void setLevel(String level) {this.level = level;}public int getSex() {return sex;}public void setSex(int sex) {this.sex = sex;}public String getMobilephone() {return mobilephone;}public void setMobilephone(String mobilephone) {this.mobilephone = mobilephone;}public String getImg() {return img;}public void setImg(String img) {this.img = img;}
}

3.在coder-center中的pom.xml添加依赖，把需要用的jar引进来

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.shengfeng</groupId><artifactId>coder-center</artifactId><packaging>jar</packaging><version>1.0-SNAPSHOT</version><name>coder-center</name><url>http://maven.apache.org</url><properties><!-- spring版本号 --><spring.version>3.2.11.RELEASE</spring.version></properties><dependencies><!-- 引api的jar包 --><dependency><groupId>com.shengfeng</groupId><artifactId>coder-center-api</artifactId><version>1.0-SNAPSHOT</version></dependency><!-- spring核心包 --><!-- springframe start --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-oxm</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version><scope>test</scope></dependency><!-- springframe end --><!-- dubbo的包 --><dependency><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>2.4.9</version></dependency><!-- zookeeper的包 --><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>3.4.6</version><type>pom</type></dependency><dependency><groupId>com.101tec</groupId><artifactId>zkclient</artifactId><version>0.4</version></dependency></dependencies>
</project>

4.在coder-center中实现coder-center-api的接口

package com.shengfeng.user.service.impl;
import com.shengfeng.user.bean.UserBean;
import com.shengfeng.user.service.UserService;
/***  UserService impl **/
public class UserServiceImpl implements UserService {public long addUser() {return 0;}public UserBean getUserByUserId() {UserBean userBean = new UserBean();userBean.setUsername("shengfeng");return userBean;}
}

5.在coder-center中将实现的服务暴露出来，provider.xml配置文件如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd  http://code.alibabatech.com/schema/dubbo  http://code.alibabatech.com/schema/dubbo/dubbo.xsd"><!-- 提供方应用信息，用于计算依赖关系 --><dubbo:application name="coder-center-provider" /><!-- 使用zookeeper注册中心暴露服务地址 --><dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" /><!-- 用dubbo协议在20880端口暴露服务 --><dubbo:protocol name="dubbo" port="20880" /><!-- 声明需要暴露的服务接口 --><dubbo:service interface="com.shengfeng.user.service.UserService"ref="userService" /><bean id="userService" class="com.shengfeng.user.service.impl.UserServiceImpl" />
</beans>

6.服务启动类

package com.shengfeng.user.main;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Provider {public static  ClassPathXmlApplicationContext context;public static void main(String[] args) {context = new ClassPathXmlApplicationContext(new String[] { "provider.xml" });context.start();System.out.println("coder-center 启动成功");while (true) {try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}}
}

7.启动main方法之后，去dubbo-admin管理平台上看是否已经将提供的服务暴露到上面

查看提供者

这样就完成了一半，还剩下一个消费者

三.服务消费者

1.在appserver项目中先在pom.xml文件中引入相应的jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.shengfeng</groupId><artifactId>appserver</artifactId><packaging>war</packaging><version>1.0</version><name>appserver Maven Webapp</name><url>http://maven.apache.org</url><build><finalName>appserver</finalName></build><properties><!-- spring版本号 --><spring.version>3.2.11.RELEASE</spring.version></properties><dependencies><!-- 引api的jar包 --><dependency><groupId>com.shengfeng</groupId><artifactId>coder-center-api</artifactId><version>1.0-SNAPSHOT</version></dependency><!-- spring核心包 --><!-- springframe start --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-oxm</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version><scope>test</scope></dependency><!-- springframe end --><!-- dubbo的包 --><dependency><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>2.4.9</version></dependency><!-- zookeeper的包 --><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>3.4.6</version><type>pom</type></dependency><dependency><groupId>com.101tec</groupId><artifactId>zkclient</artifactId><version>0.4</version></dependency></dependencies>
</project>

2.消费服务的类UserAction

package com.shengfeng.user.action;
import java.io.IOException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.shengfeng.user.service.UserService;
public class UserAction {public static void main(String[] args) throws IOException {ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "consumer.xml" });context.start();System.out.println("consumer启动成功");UserService userService = (UserService) context.getBean("userService");System.out.println("username:" + userService.getUserByUserId().getUsername());while (true) {try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}}
}

这里需要说一下，不要消费完服务就关闭，这样的话它都到不了注册中心那里，也就是dubbo-admin那里的消费者一直会显示不出来，这里的解决办法是让它睡1秒

3.消费服务的配置文件consumer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd  http://code.alibabatech.com/schema/dubbo  http://code.alibabatech.com/schema/dubbo/dubbo.xsd"><!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样  --><dubbo:application name="consumer-appserver" /><!-- 使用zookeeper注册中心暴露发现服务地址 --><dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" default="true"/><!-- 引入服务接口 --><dubbo:reference id="userService" interface="com.shengfeng.user.service.UserService" />
</beans>

4.启动UserAction的main方法，然后去dubbo-admin管理平台上去看是否有消费者的相应信息

查看消费者

然后可以在eclipse控制上看到可以消费到 提供者提供的服务

比较简单，不过可以试试手~
